Abstract:
AbstractOur purpose in writing this article is two-fold. First , we will provide a brief description of the incorporation process in Romania, the evolution thereof, and the policies that support the process. This description will also include a brief comparison of Delaware law and practice. We have selected Delaware since, among other (perceived) benefi ts offered to investors, the Delaware spirit refl ects the liberal corporate policies that many observers believe attract entrepreneurs to that state. On one hand, the process of establishing a business entity has been wiped clean of formalism, thereby accelerating the procedure to the point that incorporation can generally be realized in less than one day. On the other hand, the corporate governance legal framework (both statutory and case law) allows investors to shape their business activity in almost any manner they desire. Second , it offers a set of recommendations for further improving shareholders' "freedom of contract"—the institution that opposes traditional continental doctrines justifying state interventionism in economic ventures.

Abstract:
This research explores the meaning, construction, representation, and function of Delaware ethnic identity during the 1820s. In 1821, nearly 2,000 Delawares (self-referentially called Lenape) crossed the Mississippi River and settled in Southwest Missouri as a condition of the Treaty of St. Marys. This dissertation argues that effects of this emigration sparked a vigorous reconsideration of ethnic identity and cultural representation. Traditionally, other Eastern Algonquian groups recognized Delawares by the metaphoric kinship status of "grandfather." Both European and Colonial governments also established Delawares as preferential clients and trading partners. Yet, as the Delawares immigrated into a new "western" Superintendency of Indian Affairs in 1821, neither status was acknowledged. as a result, Delaware representations transitioned from a taken-for-granted state into an actively negotiated field of discourse. This dissertation utilizes numerous unpublished primary source documents and archaeological data recovered during the Delaware Town Archaeological Project (2003-2005) to demonstrate the social, political, and material consequences of Delaware ethnic identity revitalization. Utilizing Silliman's (2001) practical politics model of practice theory, the archival and archaeological data sets of Delaware Town reveal the reinforcement of conspicuous ethnic boundaries, coalition-building that emphasized Delaware status as both "grandfathers" and as warriors, and also reestablishing preferred client status in trade and treaty-making. This study illuminates this poorly-known decade as a time where Delawares negotiated and exerted their ethnic identity and cultural representations to affect political, economic, and social outcomes of their choosing in the rapidly-vanishing "middle ground" of early-19th century Missouri.

Abstract:
When they resided along the White River in Indiana from 1790 to 1821, the Lenape culture exhibited a blend of traits created by contact with European and other Native American groups. This has made observing the Lenape culture archaeologically problematic, especially the village of Wapicomekoke. In searching for this site, several research questions were addressed including who the Lenape were during this time period and what type of material culture would be associated with them. By compiling a brief history of the Lenape, the archaeological evidence associated with these encounters, and ethnohistoric data pertaining to the life of the Lenape at Wapicomekoke, it can be predicted that the archaeological site associated with this historic location would show evidence of log cabins, a large central longhouse, and of daily activities such as food preparation, dress, and trade goods use as well as Lenape specific items such as the “Delaware dolls.”

Abstract:
History
M.A.
This paper seeks to understand how the Seventeenth-century Lenape Indians were pushed off their Delaware River land by Europeans, starting with the so-called good colonists: the Swedes and Finns. From the time of earliest Lenape and European contact in the 1630’s through mid-century, the Lenape held power in their homeland, Lenapewhittuck, along the Delaware River. By 1700, English colonizers had succeeded in removing many Lenape from this area. A closer examination of this period reveals how the Swedes and Finns of New Sweden who in some current historiographies are promoted as ‘good colonizers,’ were anything but as they acted in their own self-interest through their focus on daily survival and individual land acquisition around the Delaware River. Their presence created conditions that attracted increased numbers of European colonizers to the area, and these colonizers through the creation of a market in land pushed the Lenape away from their homeland. Recent historiography has revealed how the Seventeenth-century Lenape Indians were a powerful group who controlled their land. By understanding the Lenape in this way, Swedish and Dutch accounts of Indian and European violence and peacemaking coalesce to reveal Lenape power in the region. ‘Seeing’ Lenape power reveals how the creation of a European land market along the Delaware was key in tipping this balance in power that ensured Lenape departure. Swedish and Finnish possession of the area, when combined with the ability to securely own the land one farmed and pass that land to heirs, invited increasing numbers of settler colonists into the area. Translated land treaties made between the Lenape, the Dutch, and the Swedes and later English land survey deeds provide evidence of the establishment of a market in land along the Delaware River. Court records from the 1650’s recorded land transactions that demonstrate the incursion of individual European settler colonists through a newly established economic condition: individual land ownership. As more Europeans entered the area to possess land through their understanding of land use, these individual settler colonists challenged former Lenape land ‘sale’ treaty terms that had included the condition of shared usufruct rights. Overtime, this understanding changed as European land owners grew to regard their possession of land as ownership, to the exclusion of other Europeans and the Lenape.

Abstract:
In 1767 David Zeisberger began his Moravian mission to the Delaware Indians in Ohio. He led this mission until his death in 1808. While Zeisberger and his assistants required conformity in matters religious, the converts did not have to make enormous changes in their traditional beliefs. The Delaware converts also did not have to alter their traditional economic, medical, housing, and diplomatic practices.;The goal of this study is to understand why hundreds of Delawares chose to convert, and why as many more chose to live at the mission. Many Delawares hoped to return to the peaceful life they had previously enjoyed. Many chiefs joined the mission and maintained their influence within the mission structure, and many followed these important men to the mission, believing that the latter must "know something right." Others joined the mission because family members had converted. Many came to live at the mission to escape the destruction and danger of the revolutionary war, while others came to find an escape from the increasing disruption of drunkenness and witchcraft.;Previous studies have failed either to study the full chronological scope of the mission or have made serious errors in their conclusions. Unlike previous studies, it analyzes the structure and operations of the mission and the changes that were required of the converts.;Zeisberger's success lay not only in the numbers of converts he gained but also in the relationships he forged with the Delaware and other Indian nations of Ohio. Even in the worst of circumstances, the Delaware converts chose to remain with or rejoin the mission. at all times Zeisberger managed to maintain friendly relations with most nations, even during times of war. Because of his leadership and tolerance, the converts continued to identify themselves as Delaware Indians; altering their religion did not remove their primary identity nor their sense of loyalty to their people. The converts, although now Moravian in faith, remained Delawares.

History
Ph.D.
This dissertation uncovers women healers' vital role in the eighteenth- and early nineteenth-century healthcare marketplace. Euro-American women healers participated in networks of health information sharing that reached across lines of class and gender, and included female practitioners in American Indian and African American communities. Although their contributions to the healthcare labor force are relatively invisible in the historical record, women healers in the Delaware Valley provided the bulk of healthcare for their families and communities. Nonetheless, apart from a few notable monographs, women healers' practices and authority remain understudied. My project complicates a medical historiography that marginalizes female practitioners and narrates their declining healthcare authority after the mid-eighteenth century due to the emergence of a consumer society, a culture of domesticity, the professionalization of medicine, and the rise of enlightened science, which generated discourses of women's innate irrationality. Using the Philadelphia area as a case study, I argue that women healers were not merely static traditional practitioners destined to fall victim to the march of science, medicine, and capitalism as this older narrative suggests. Instead, I assert that women healers of various classes and ethnicities adapted their practices as they found new sources of healthcare authority through female education in the sciences, manuscript authorship, access to medical print media, the culture of sensibility, and the alternative gender norms of religious groups like the Quakers. Building on a longstanding foundation of recognized female practitioners, medically skilled women continued to fashion healing authority by participating in mutually affirming webs of medical information exchanges that reflected new ideas about science, health, and the body. In addition, women doctresses, herbalists, apothecaries, and druggists empowered themselves by participating in an increasingly commercialized and consumer-oriented healthcare marketplace. Within this unregulated environment, women healers in the colonies and early republic challenged physicians' claims to a monopoly on medical knowledge and practice. The practitioners analyzed in this study represent a bridge between the recognized and skilled women healers of the seventeenth century and the female healthcare professionals of the nineteenth century.

Abstract:
History
Ph.D.
An ever-present figure throughout much of the nineteenth century, the prostitute existed in a state divorced from "traditional" womanhood as a shadowy yet "necessary" evil, and was largely seen as a static element of the city. The archetypes of the "endangered maiden" and the "fallen woman" were discursive creations evolving from an inchoate form to a more sharply defined state that were designed to explain the prostitute's continued existence despite the moral objections voiced by religious and social reformers. These archetypes functioned in an agrarian/proto-industrial society; however, under pressures of urbanization, industrialization, and population mobility, these archetypes were gradually supplanted by sharper, more emotionally loaded archetypes such as the "White Slave" and the trope of the "Vice Syndicate" to explain the prostitute. In this manner Progressive-Era social and moral reformers could interpret prostitution in general and the prostitute in particular within the framework of their understanding of a contentious social environment. In moving away from a religious framework towards a more scientific interpretation, the concept of prostitution evolved from a moral failing to a status analogous to a disease that infected the social body of the state. However, because the White Slave and the Vice Syndicate were discursive creations based upon anecdotal interpretations of prostitution as a predatory economic system, their nebulous nature encouraged a crisis mentality that could not survive a concrete examination of their "problem." Realities of race, class, and gender, as well as the fluid nature of the urban environment as well as non-moral concerns rendered the new archetypes and tropes slippery, and applicable to any reform-oriented argument. By the later years of the Progressive Era anti-vice discourse ceased to advocate moral arguments calling for the rescue of the prostitute and instead became a vehicle to articulate non-moral concerns such as political reform, social order, and female economic suffrage. After the First World War, the archetype of the White Slave collapsed in the face of women's suffrage and sexual agency, and the prostitute once more reverted to a state analogous to pre-Progressive cultural interpretations of prostitution.

Full text
Abstract:
Abstract This Delaware Basin case history describes a bradenhead cementing method that improves zonal isolation and top of cement (TOC). Common solutions for cementing depleted formations include stage tools, low-density slurries and reverse circulation. For this bradenhead method, cement is pumped through the wellhead valves and down the annulus to a target loss zone. Field data, lab data and the engineering model support the improvement bradenhead cementing provides across depleted formations. The depleted Brushy Canyon formation serves as an injection interval for a two-stage bradenhead cement job. This approach isolates formations below the Brushy Canyon with a conventional first stage, while achieving TOC with the second stage pumped down the annulus. Fracture gradients of the injection interval and casing shoe constrain the cement design. To achieve adequate cement placement, the design phase includes the pressure calculations required to initiate flow and injection for the bradenhead stage. Reactive spacers are utilized to prevent annulus fluid level drop in extreme cases. A benchmarked cement bond log (CBL) quantifies the results and validates this unconventional cementing method. More than 50 two-stage bradenhead cement jobs were executed with a TOC success rate of 100% in intermediate and production hole applications. CBL data obtained after cementing the intermediate casing confirms the two-stage bradenhead as a placement method. In areas constrained by casing shoe pressures, CBL data identified potential areas of shallow injection. These data resulted in a modification of the fluids pumped. Use of these re-engineered fluids reduced injection initiation pressures and improved cement bonding across salt and anhydrite formations. Cementing costs were reduced by eliminating stage tools, annular casing packers, and low-density cement slurries. Pumping the bradenhead job offline (off the rig's critical path) reduces cost further. These features support bradenhead cementing as an effective solution for wellbore sections with a potential injection zone. The regulatory requirement to place cement above depleted formations resulted in many innovative cementing methods. Stage tools, low-density slurries, and reverse circulation are attempts to avoid formation breakdown, but these methods increase cost and have limited reliability and integrity. Bradenhead cementing takes advantage of the depleted interval to aid in cement placement. Although counterintuitive, bradenhead cementing has proved to be a cost-effective solution that improves zonal isolation and eliminates integrity risks associated with stage tool failures.

Full text
Abstract:
Abstract The Delaware Basin encompasses 6.4 million acres throughout Southeastern New Mexico and West Texas. With large players such as ExxonMobil, Shell or Oxy typically grabbing headlines, it's easy to forget the multitude of smaller public and private E&P operators who exist in and around the acreage positions of the aforementioned companies. Regardless of the size of the acreage holding, a consistent theme is that a typical horizontal well drilled and completed (D&C) will yield water cuts of 60-90% at any given period in its productive lifespan. Saltwater production, handling and disposal (SWD) is a drag on lease operating expenses (LOE). SWD costs via trucking, pipeline, or on-lease SWD wells can range between $0.50-$3.00/bbl. As existing infrastructure is exhausted, water handling costs have been projected to rise to over $5.00/bbl. Additionally, restricted access to SWD could cause production curtailments and thus impacting operators beyond direct LOE.1 Well completion operations are impacted by freshwater procurement costs starting around $0.75/bbl. Regardless of final frac design, water consumption during fracturing operations typically exceeds 500,000 bbls or $375,000 per well. Significant value exists for recycling produced water via an on-lease pit and utilizing it for future frac operations. The produced water turns into an asset if the operator can efficiently manage to substitute higher and higher percentages of freshwater with produced water. Many smaller operators (defined as less than 50,000 acres) may view produced water recycling as an operation best left to large E&P's with their massive capital budgets and contiguous acreage. Fortunately, even a 5 well, section development plan can yield returns from an on-lease produced water recycling program.

Abstract:
Abstract Predicting fracture behavior is important for well placement design and for optimizing multi-well development production. This requires the use of fracturing models that are calibrated to represent field measurements. However, because hydraulic fracture models include complex physics and uncertainties and have many variables defining these, the problem of calibrating modeling results with field responses is ill-posed. There are more model variables than can be changed than field observations to constrain these. It is always possible to find a calibrated model that reproduces the field data. However, the model is not unique and multiple matching solutions exist. The objective and scope of this work is to define a workflow for constraining these solutions and obtaining a more representative model for forecasting and optimization. We used field data from a multi-pad project in the Delaware play, with actual pump schedules, frac sequence, and time delays as used in the field, for all stages and all wells. We constructed a hydraulic fracturing model using high-confidence rock properties data and calibrated the model to field stimulation treatment data varying the two model variables with highest uncertainty: tectonic strain and average leak-off coefficient, while keeping all other model variables fixed. By reducing the number of adjusting model variables for calibration, we significantly lower the potential for over-fitting. Using an ultra-fast hydraulic fracturing simulator, we solved a global optimization problem to minimize the mismatch between the ISIPs and treatment pressures measured in the field and simulated by the model, for all the stages and all wells. This workflow helps us match the dominant ISIP trends in the field data and delivers higher confidence predictions in the regional stress. However, the uncertainty in the fracture geometry is still large. We also compared these results with traditional workflows that rely on selecting representative stages for calibration to field data. Results show that our workflow defines a better global optimum that best represents the behavior of all stages on all wells, and allows us to provide higher-confidence predictions of fracturing results for subsequent pads. We then used this higher confidence model to conduct sensitivity analysis for improving the well placement in subsequent pads and compared the results of the model predictions with the actual pad results.

Abstract:
Abstract PVT fluid systems vary across the Delaware Basin in Texas, transitioning from black oil in eastern Loving County to volatile oil in the center of northern Loving County, shifting to near-critical fluid or rich gas condensate on the western part of Reeves County. Understanding the GOR behavior of a near-critical fluid system is important for meaningful reserves estimation, optimal well spacing, and efficient completion design. GOR behavior is controlled by PVT fluid system, the initial reservoir conditions, rock-fluid properties, the effective SRV (Stimulated Rock Volume) achieved by hydraulic fracturing, the flow regimes in the dual matrix-fracture system, inter-well communications, and well drawdown strategy. The system pressure and flow regimes developed in the Trilinear system (Brown et al. 2011) of inner fracture plane, outer fracture network, and surrounding tight matrix control the GOR profile shape. The producing GOR of Wolfcamp formations in the Delaware Basin typically exhibits a long GOR transient plateau, which is controlled by the PVT fluid system, the degree of undersaturation, the Linear Flow Parameter (LFP), fracture network complexity, and the contacted OOIP in the SRV. In this study, numerical multiphase RTA modeling was performed for Wolfcamp wells in the near-critical PVT regions. GOR remains constant during the linear transient flow regime; late-time gradual rise in GOR is controlled by LFP/OOIP ratios, which are determined by history matching the linear flow to the boundary-dominated flow curve. The long-term production forecast was accomplished using an integrated EOS (Equation of State) compositional model. The forecast captured GOR behaviors for section-level infill development, which demonstrated long period of constant GOR followed by a gradual rise in GOR. The EOS model was characterized to represent the near-critical fluid system and was tuned using the regional PVT control points. The simulation model was upscaled from the regional subsurface geomodel with facies-controlled petrophysical properties. By incorporating the HFTS II project learnings (Bessa et al. 2021), a GOHFER fracture model was built based on standard completion designs, from which the representative SRV profiles were extracted. The key rock-fluid properties, SRV and completion efficiency, and well spacing configurations were investigated through the history matching process and sensitivity analysis. The integrated analytical and numerical modeling workflow captures the generalized GOR profiles for the Wolfcamp formation in Delaware Basin for three PVT regions: Volatile Oil, Near-Critical Fluid, and Rich Gas Condensate. It also provides a systematic approach for GOR profile construction for given PVT fluid system. Late -time rising GOR in Delaware Basin do not adversely affect the oil EUR as approximately half of the oil recovery was still achieved during rising GOR period. High pressure gradient and high degree of under-saturation is one of the main reasons for long period of constant GOR followed by gentle climb at late-time, which also provides solution gas support for oil recovery. Finally, a regional performance coefficient was proposed for ranking field development based on the PVT fluid system, the degree of under-saturation, and the completion efficiency.

Abstract:
Harpers Ferry National Historical Park (NHP) includes grassland habitats that are maintained for the interpretation of historic Civil War battles. In 2022, as part of the National Park Service Inventory and Monitoring program, the University of Delaware conducted a grassland bird and raptor inventory in the park. The goals of this inventory were to determine the grassland bird use of Harpers Ferry grasslands during Spring and Fall migration, estimate the abundance and daily nest survival for focal breeding species, and determine the raptor use during migration. We established and used multiple avian sampling techniques to address these goals including distance sampling using line transects, mist-netting to capture passerine birds, point counts, hawk watching, and nest searching and monitoring. We conducted this inventory during the annual cycle starting in March 2022 and completed the sampling in October 2022. During the course of this effort, we detected 111 species using the Harpers Ferry grasslands at some time during the year. We found that the park is supporting migrating and breeding grassland birds and that the avian species composition changes over the course of the annual cycle. During migration, we detected focal grassland bird species including Bobolink, Savannah Sparrow, Grasshopper Sparrow, and Eastern Meadowlark. During the breeding season, we located and monitored Eastern Meadowlark and Grasshopper Sparrow nests with adequate sample sizes to estimate daily nest survival. We found that Eastern Meadowlark daily nest survival was relatively high (99%) and was influenced by the proximity of the nest to a forested edge. We recommend the park focus on Eastern Meadowlark and Grasshopper Sparrows as these two species used the park during both Spring and Fall migrations and successfully fledged young during the breeding season. The park could attempt to maintain or enhance Eastern Meadowlark and Grasshopper Sparrow use of the park during all stages of the annual cycle but especially during the breeding season. This could be achieved by continuing to keep the existing breeding areas intact through delayed mowing (no mowing from 15 May ? 15 July), removing tree lines and woody or non-native vegetation to increase the perceived openness and grassland patch size, and continuing to monitor the effects of any management actions that may influence grassland bird use of Harpers Ferry NHP. Grassland birds are a national conservation priority so any sites that have the capacity to maintain or enhance these declining habitat specialists should do so. Grassland birds provide an opportunity to integrate cultural and natural resources as these birds were most certainly present prior to, during, and after the Civil War Battles that Harpers Ferry was established to commemorate.
